Since this serum actually comes in bar form, you can use it to massage your face. It's quite rich and moisturizing, and thanks to the calamine and zinc in the formula, it's great for calming redness as well.
This is technically a solid toner as opposed to serum, but it still works much in the same way as the other products on this list: You just swipe it straight on after cleansing and it adds in some extra skin-conditioning moisture (along with a pleasant cooling effect).
